<h3>Answer:    y = (3/2)x + 0</h3>

This is the same as  y = (3/2)x

=============================================================

Work Shown:

Find the slope of the line through (x1,y1) = (-2,-3) and (x2,y2) = (2,3)

m = (y2 - y1)/(x2 - x1)

m = (3 - (-3))/(2 - (-2))

m = (3 + 3)/(2 + 2)

m = 6/4

m = 3/2

The slope is the fraction 3/2. This is going to be in front of the x, or to the left of the x.

----------

Plug m = 3/2 and (x1,y1) = (-2,-3) into the point slope formula. Solve for y.

y - y1 = m(x - x1)

y - (-3) = (3/2)(x - (-2))

y + 3 = (3/2)(x + 2)

y + 3 = (3/2)x + (3/2)(2)

y + 3 = (3/2)*x + 3

y + 3 - 3 = (3/2)*x + 3 - 3

y = (3/2)x + 0

The y intercept is zero. This matches up with the fact the graph crosses the y axis at y = 0.

What single transformation was applied to triangle A to get triangle B? Links will be reported​
Alina [70]

Answer:

Rotation:

Step-by-step explanation:

Translation is usually movements like up, down, left, right.

Dilation is when one shape is bigger/smaller than the other, but still congruent.

Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

The lengths of the sides of the triangle are 3, 8, and 10. Is the triangle a right triangle, acute triangle, or an obtuse triang
weqwewe [10]

Answer:

Obtuse

Step-by-step explanation:

  1. You have to make sure it is a triangle by adding the smallest and the medium sides, if the result is greater than the bigger side then it is a triangle.
  2. you then use the Pythagorean theorem to check if the triangle is a right triangle, acute, or obtuse. If c^{2} = a^{2} +b^{2} then it is a right triangle. If c^{2} >a^{2} + b^{2} then it is an obtuse triangle. if c^{2} < a^{2} +b^{2} then it is an acute triangle.
  1. 10^{2} _ 3^{2} + 8^{2}
  2. 9+64_100
  3. 70_100
  4. 70<100

in this case c^{2} is greater than a^{2} +b^{2} therefore, is it an obtuse triangle.
